A flaw was found in the Linux kernel's Intelligent Platform Management Interface (IPMI) subsystem. This vulnerability occurs when the kernel processes event message buffer responses from Baseboard Management Controllers (BMCs). Some BMCs may return an empty message instead of an expected error, which the kernel did not properly handle. This could lead to unexpected behavior or system instability due to improper data processing.
